How can I get Optimism in ETH?

Could you please elaborate on the process of acquiring Optimism tokens using Ethereum (ETH)? I'm interested in understanding the steps involved in obtaining these tokens and what factors I should consider when making such a transaction. Is it possible to buy Optimism directly with ETH? If not, what are the alternative methods available? Additionally, could you provide any insights on the current market conditions for Optimism and any potential risks or considerations I should be aware of before proceeding with the purchase? I'm seeking clarity and advice from an expert in the field to ensure I make an informed decision. Thank you in advance for your assistance.
